http://www.ses.vic.gov.au/prepare/em-planning/local-knowledge

Part 3. RESPONSE ARRANGEMENTS

3.1 Introduction

3.1.1 Activation of Response

Flood response arrangements may be activated by the VICSES Hume Regional Duty Officer (RDO) or Incident Controller.

The Incident Controller/RDO will activate agencies as required and documented in the State Flood Emergency Management Plan.

3.1.2 Responsibilities

There are a number of agencies with specific roles that will act in support of VICSES and the community in the event of a serious flood within the Rural City of Wangaratta. These agencies will be engaged through the EMT.

The general roles and responsibilities of supporting agencies are as agreed within the Rural City of Wangaratta MEMP, EMMV (Part 7 ‘Emergency Management Agency Roles’), State Flood Emergency Plan and Regional Flood Emergency Plan.

3.1.3 Municipal Emergency Coordination Centre (MECC)

Liaison with the MECC will be through the established Division/Sector Command and through Municipal involvement in the Incident EMT, in particular the Municipal Emergency Response Coordinator (MERC). The VICSES RDO / ICC will liaise with the MECC directly if no Division/Sector Command is established.

The function, location, establishment and operation of the MECC will be as per the Rural City of Wangaratta MEMP.

3.1.4 Escalation

Most flood incidents are of local concern and an appropriate response can usually be coordinated using local resources. However, when these resources are exhausted, the State’s arrangements Rural City of Wangaratta Flood Emergency Plan – A Sub-Plan of the Municipal Emergency Management Plan

- 15 -

provide for further resources to be made available, firstly from neighbouring Municipalities (on a regional basis) and then on a State-wide basis.

Resourcing and event escalation arrangements are described in the EMMV (‘State Emergency Response Plan’ – section 3.5).

3.2 Strategic Control Priorities To provide guidance to the Incident Management Team (IMT), the following strategic control priorities shall form the basis of incident action planning processes: 1. Protection and preservation of life is paramount - this includes:

a. Safety of emergency services personnel, and;

b. Safety of community members including vulnerable community members and visitors/tourist located within the incident area.

2. Issuing of community information and community warnings detailing incident information that is timely, relevant and tailored to assist community members make informed decisions about their safety.;

3. Protection of critical infrastructure and community assets that supports community resilience;

4. Protection of residential property as a place of primary residence;

5. Protection of assets supporting individual livelihoods and economic production that supports individual and community financial sustainability

6. Protection of environmental and conservation values that considers the cultural, biodiversity, and social values of the environment;

Circumstances may arise where the Incident Controller is required to vary these priorities, with the exception being that the protection of life should remain the highest. This shall be done in consultation with the State Controller and relevant stakeholders based on sound incident predictions and risk assessments.

3.3 Command, Control & Coordination The Command, Control and Coordination arrangements in this Municipal Flood Emergency Plan must be consistent with those detailed in State and Regional Flood Emergency Plans. For further information, refer to sections 3.4, 3.5 & 3.6 of the EMMV. The specific details of the Command, Control and Coordination arrangements for this plan are to be provided in Appendix C.

3.3.1 Control

Functions 5(a) and 5(c) at Part 2 of the Victoria State Emergency Service Act 1986 (as amended) detail the authority for VICSES to plan for and respond to flood.

Part 7.1 of the EMMV prepared under the Emergency Management Act 1986 (as amended), identifies VICSES as the Control Agency for flood. It identifies DSE (now DEPI) as the Control Agency responsible for “dam safety, water and sewerage asset related incidents” and other emergencies

Rural City of Wangaratta Flood Emergency Plan – A Sub-Plan of the Municipal Emergency Management Plan

- 16 -

All flood response activities within the Rural City of Wangaratta including those arising from a dam failure or retarding basin / levee bank failure incident will therefore be under the control of the appointed Incident Controller, or his / her delegated representative.

3.3.2 Incident Controller (IC)

An Incident Controller (IC) will be appointed by VICSES to establish command and control of resources in response to a flood event on the advice of the Bureau of Meteorology (or other reliable source) that a flood event will occur or is occurring. The Incident Controller’s responsibilities are defined in Part 3.5 of the EMMV

3.3.3 Incident Control Centre (ICC)

As required, the Incident Controller will establish an Incident Control Centre (ICC) from which to initiate incident response command and control functions. The decision to activate the ICC rests with the Control Agency (i.e. VICSES).

Incident Control Centre locations are:

. CFA District 23 Headquarters 1 Ely Street, Wangaratta . VICSES Hume Regional Office 64 Sydney Road, Benalla

3.3.4 Divisions and Sectors

To ensure that effective Command and Control is in place, the Incident Controller may establish Divisions and Sectors to facilitate operational response within the Municipality. VICSES Hume Region Flood Response Plan provides a list of designated DCPs and SCPs.

VICSES Field Operations Vehicles (FOVs) are also available for deployment where appropriate.

3.3.5 Incident Management Team (IMT)

The Incident Controller will form an Incident Management Team in accordance with Agency Command & Control arrangements. .Emergency Management Team (EMT)

The Incident Controller will establish a multi-agency Emergency Management Team to assist the flood response. The EMT will consist of key personnel (with appropriate authority) from stakeholder agencies and relevant organisations who need to be informed of strategic issues related to incident control. They will provide high level strategic guidance and policy advice to the Incident Controller for consideration in developing incident management strategies. Organisations, including Rural City of Wangaratta, required within the EMT will provide an Emergency Management Liaison Officer (EMLO) to the ICC when required as well as other staff and / or resources identified as being necessary, within the capacity of the organisation. Refer to 3.5 of the EMMV for guidance on EMTs.

3.3.6 On Receipt of a Flood Watch / Severe Weather Warning

Incident Controller or VICSES RDO (until an incident controller is appointed) will undertake actions as defined within the flood intelligence cards (Appendix C). General considerations by the Incident Controller/VICSES RDO will be as follows: . Review flood intelligence to assess likely flood consequences Rural City of Wangaratta Flood Emergency Plan – A Sub-Plan of the Municipal Emergency Management Plan

- 17 -

. Monitor weather and flood information – www.bom.gov.au . Assess Command and Control requirements. . Review local resources and consider needs for further resources regarding personnel, property protection, flood rescue and air support . Notify and brief appropriate officers. This includes Regional Control Centre (RCC) (if established), State Control Centre (SCC) (if established), Council, other emergency services through the EMT. . Assess ICC readiness (including staffing of IMT and EMT) and open if required . Ensure flood bulletins and community information are prepared and issued to the community . Monitor watercourses and undertake reconnaissance of low-lying areas . Develop media and community information management strategy . Ensure flood mitigation works are being checked by owners . Develop and issue incident action plan, if required . Develop and issue situation report, if required

3.3.7 On Receipt of the First and Subsequent Flood Warnings

Incident Controller/VICSES RDO (until an incident controller is appointed) will undertake actions as defined within the flood intelligence cards (Appendix C). General considerations by the Incident Controller/VICSES RDO will be as follows: . Develop an appreciation of current flood levels and predicted levels. Are floodwaters, rising, peaking or falling? . Review flood intelligence to assess likely flood consequences. Consider:  What areas may be at risk of inundation

 What areas may be at risk of isolation

 What areas may be at risk of indirect affects as a consequence of power, gas, water, telephone, sewerage, health, transport or emergency service infrastructure interruption

 The characteristics of the populations at risk . Determine what the at-risk community need to know and do as the flood develops. . Warn the at-risk community including ensuring that an appropriate warning and community information strategy is implemented including details of:

 The current flood situation

 Flood predictions

 What the consequences of predicted levels may be

 Public safety advice

 Who to contact for further information  Who to contact for emergency assistance . Liaise with relevant asset owners as appropriate (i.e. water and power utilities) . Implement response strategies as required based upon flood consequence assessment. . Continue to monitor the flood situation – www.bom.gov.au/vic/flood/

Rural City of Wangaratta Flood Emergency Plan – A Sub-Plan of the Municipal Emergency Management Plan

- 18 -

. Continue to conduct reconnaissance of low-lying areas

3.4 Community Information and Warnings Guidelines for the distribution of community information and warnings are contained in the State Flood Emergency Plan.

Community information and warnings communication methods available include: . Emergency Alert; . Phone messages (including SMS); . Radio and Television; . Two-way radio; . Mobile and fixed public address systems; . Sirens; . Verbal Messages (i.e. Doorknocking); . Agency Websites; . VICSES Flood Storm Information Line; . Variable Message Signs (i.e. road signs); . Community meetings; . Newspapers; . Email; . Telephone trees; . Community Flood Wardens; . Fax Stream; . Newsletters; . Letter drops; . Social media and/or social networking sites (i.e. Twitter and/or Facebook). Refer to Appendices C and E for the specific details of how community information and warnings are to be provided.

The release of flood bulletins and information with regard to response activities at the time of a flood event is the responsibility of VICSES.

Council has the responsibility to assist VICSES to warn individuals within the community including activation of flood warning systems, where they exist. Responsibility for public information, including media briefings, rests with VICSES.

Other agencies such as CFA, DEPI and VICPOL may be requested to assist VICSES with the communication of community flood warnings. In cases where severe flash flooding is predicted, dam failure is likely or flooding necessitating evacuation of communities is predicted, the Incident Controller may consider the use of the Emergency Alert System and Standard Emergency Warning System (SEWS).

Rural City of Wangaratta Flood Emergency Plan – A Sub-Plan of the Municipal Emergency Management Plan

- 19 -

Department of Health will coordinate information regarding public health and safety precautions.

3.5 Media Communication The Incident Controller, through the Information Unit established at the ICC, will manage media communication. If the ICC is not established the VICSES RDO will manage media communication.

3.6 (Initial) Rapid impact assessment An (initial) rapid impact assessment can be conducted in accordance with part 3 of the EMMV to assess and record the extent and nature of damage caused by flooding. This information may then be used to provide the basis for further needs assessment and recovery planning by DHS and recovery agencies.

3.7 Preliminary Deployments When flooding is expected to be severe enough to cut access to towns, suburbs and/or communities the Incident Controller will consult with relevant agencies to ensure that resources are in place if required to provide emergency response. These resources might include emergency service personnel, food items and non-food items such as medical supplies, shelter, assembly areas, relief centres etc.

3.8 Response to Flash Flooding Emergency management response to flash flooding should be consistent with the guideline for the emergency management of flash flooding contained within the State Flood Emergency Plan.

When conducting pre-event planning for flash floods the following steps should be followed, and in the order as given:

1. Determine if there are barriers to evacuation by considering warning time, safe routes, resources available and etc;

2. If evacuation is possible, then evacuation should be the adopted strategy and it must be supported by a public information capability and a rescue contingency plan;

3. Where it is likely people will become trapped by floodwaters due to limited evacuation options safety advice needs to be provided to people at risk advising them not to attempt to flee by entering floodwater if they become trapped, and that it may be safer to seek the highest point within the building and to telephone 000 if they require rescue. This advice needs to be provided even when evacuation may be possible, due the likelihood that not all community members will evacuate.

4. For buildings known to be structurally un-suitable an earlier evacuation trigger will need to be established (return to step 1 of this cycle).

5. If an earlier evacuation is not possible then specific preparations must be made to rescue occupants trapped in structurally unsuitable buildings either pre-emptively or as those people call for help.

During a flash flood it will often be difficult, due the rapid development of flooding, to establish evacuation (relief) centres ahead of actually triggering the evacuation as is normal practice but this is insufficient justification for not adopting evacuation.

Refer to Appendix C for response arrangements for flash flood events.

Rural City of Wangaratta Flood Emergency Plan – A Sub-Plan of the Municipal Emergency Management Plan

- 20 -

3.9 Evacuation The decision to recommend or warn people to prepare for evacuation, or to evacuate immediately, rests with the Incident Controller.

Once the decision is made VicPol are responsible for the management of the evacuation process. VICSES and other agencies will assist where practical. VICSES is responsible for the development and communication of evacuation warnings.

VicPol and/or Australian Red Cross may take on the responsibility of registering people affected by a flood emergency including those who have been evacuated.

Refer to section 3.8 of the EMMV and the Evacuation Guidelines for guidance of evacuations for flood emergencies.

Refer to Appendix C of this Plan for detailed evacuation arrangements for Rural City of Wangaratta.

3.10 Flood Rescue Appropriately trained and equipped VICSES/VicPol units or other agencies that have appropriate training, equipment and support may carry out rescues. Rescue operations may be undertaken where voluntary evacuation is not possible, has failed or is considered too dangerous for an at-risk person or community. An assessment of available flood rescue resources (if not already done prior to the event) should be undertaken prior to the commencement of rescue operations.

Rescue is considered a high-risk strategy to both rescuers and persons requiring rescue and should not be regarded as a preferred emergency management strategy. Rescuers should always undertake a dynamic risk assessment before attempting to undertake a flood rescue.

Resources available for use for rescues to be carried out within Rural City of Wangaratta are detailed in Appendix C.

3.11 Aircraft Management Aircraft can be used for a variety of purposes during flood operations including evacuation, resupply, reconnaissance, intelligence gathering and emergency travel. Air support operations will be conducted under the control of the Incident Controller.

The Incident Controller may request aircraft support through the State Air Desk located at the State Control Centre will establish priorities. . The Wangaratta Aerodrome has sealed and grass runways. Runway 18/36 is a 1.64km long sealed runway with pilot activated lights for night landing and non-directional beacon facilities. Runway 09/27 is a 530 metre grass runway which may be closed due to wet conditions.

3.12 Resupply Communities, neighbourhoods or households can become isolated during floods as a consequence of road closures or damage to roads, bridges and causeways. Under such circumstances, the need may arise to resupply isolated communities/properties with essential items. When predictions/intelligence indicates that communities, neighbourhoods and/or households may become isolated, VICSES will advise businesses and/or households that they should stock up on essential items.

Rural City of Wangaratta Flood Emergency Plan – A Sub-Plan of the Municipal Emergency Management Plan

- 21 -

After the impact, VICSES can support isolated communities through assisting with the transport of essential items to isolated communities and assisting with logistics functions.

Resupply operations are to be included as part of the emergency relief arrangements with VICSES working with the relief agencies to service communities that are isolated.

3.13 Essential Community Infrastructure and Property Protection Essential Community Infrastructure and Property (e.g. residences, businesses, roads, power supply etc.) may be affected in the event of a flood. The Rural City of Wangaratta maintains a minimum stock of 3,000 sandbags, and back-up supplies are available through the VICSES Regional Headquarters. The Incident Controller will determine the priorities related the use of sandbags, which will be consistent with the strategic priorities. If VICSES sandbags are becoming limited in supply, then priority will be given to protection of essential community infrastructure. Other high priorities may include for example the protection of historical buildings.

Property may be protected by:

 Sandbagging to minimise entry of water into buildings  Encouraging businesses and households to lift or move contents  Construction of temporary levees in consultation with the CMA, LGA and VICPOL and within appropriate approval frameworks.

The Incident Controller will ensure that owners of Essential Community Infrastructure are kept advised of the flood situation. Essential Community Infrastructure providers must keep the Incident Controller informed of their status and ongoing ability to provide services.

Refer to Appendix C for further specific details of essential infrastructure requiring protection and location of sandbag collection point(s).

3.14 Disruption to Services Disruption to services other than essential community infrastructure and property can occur in flood events.

APPENDIX A FLOOD THREATS FOR RURAL CITY of WANGARATTA

This Appendix provides a broad overview of flood risk within the Municipality. Detailed flood risk information for individual communities is provided in Appendix C for:

 C1 – River systems overview  C2 – Ovens River at Whorouly  C3 – King River from Moyhu to Cheshunt  C4 – Ovens & King Rivers – One Mile & Three Mile Creeks, Wangaratta Urban area

General The Wangaratta rural environs is a complex flood plain with the Ovens, King and 15 Mile Creek systems flowing through the Municipality joining in the Wangaratta urban area and continuing on as the Ovens River to join the Murray River at Bundalong. The upper catchment of the King River and 15 Mile Creek is prone to flash flooding events with rapid stream rises closing roads and isolating communities.

OVENS RIVER, KING RIVER & FIFTEEN MILE CREEK

The Ovens River Basin covers an area of 7,985 km2 (Source. G-MW). The area extends from the Murray River in the north, to the Great Dividing Range in the south and is bordered by the Broken River Basin in the west and the Kiewa River Basin in the east. The topography of the Basin is diverse ranging from riverine plains near the Murray River and broad alluvial valleys around Myrtleford, to rugged alpine peaks and plateaux around the Great Dividing Range.

The Ovens River flows in a north-westerly direction from the high country near Mt Feathertop and Mt Hotham. The Ovens River and its upstream tributaries - the Buckland, Catherine, Dandongadale, Buffalo and Rose rivers - have their headwaters in the Great Dividing Range, in the section extending between Mt Cobbler and Mt Hotham. . In the south-west corner of the Basin, the Ovens River passes through the townships of Harrietville, Bright, Porepunkah and Myrtleford to Wangaratta, then north- west to the Murray River.

The largest tributary, the King River, is situated south-west of the Ovens River and has its headwaters on the Great Divide near Mt Howitt. The Ovens and the King Rivers meet on the riverine plain at Wangaratta. The main storages in the basin are Lake Buffalo on the Buffalo River and Lake William Hovell on the King River.

In the central portion of the Basin, wide valleys have developed along the Ovens and King Rivers, below Wangaratta. The Ovens River takes in the water of Reedy and Fifteen Mile Creeks and meanders northward across the riverine flood plain to flow into Lake Mulwala on the Murray River

FLOOD HISTORY

Description of Major Waterways and Drains

OVENS RIVER

The Ovens River catchment is steep topography down to Rocky Point at Whorouly East. The two main tributaries are the Buckland River and the Buffalo River. Both tributaries have steep topography to their confluence with the Ovens. This all occurs in the Alpine Shire and explains the often rapid and severe flooding that occurs in that municipality in a major event, compared to the slower but more widespread flooding that affects the gradually flatter and wider floodplain between Rocky Point and Wangaratta. The steep topography in the Alpine Shire causes a rapid stream flow that minimises the ability to provide early flood warnings for that municipality based on stream flows.

From Rocky Point to Wangaratta the Ovens floodplain follows a historically defined course several kilometres wide taking in the Whorouly, Markwood, Tarrawingee and Oxley Flats areas. This is contained initially within high country at Henley Ridge and the Everton/Murmungee divide and further west between high ground around Milawa and high ground north of the Great Alpine Road. The Tea Garden Creek defines the southern boundary of much of this flood plain from Everton to Oxley Flats and smaller catchments such as Horseshoe Creek cut through the high ground south and west of Milawa. Hodgsons Creek rises in the gold country south west of Beechworth and runs westerly through Black Springs and Everton Upper to Tarrawingee where it joins the Ovens River. Reedy Creek rises in the high country around Woorragee and runs westerly through Woolshed and Eldorado and crosses the Hume Freeway north of Wangaratta from where it defines the northern edge of the Ovens River floodplain down to Boorhaman.

The combination of King River and Ovens River waters during flood times has a profound effect on properties east and north of Wangaratta on the floodplain near the confluence of the two rivers. This resulted in the construction of two major flood levees, the Parfitt Road Levee and the Wilson Road Levee in the early 1980's as part of the Wangaratta Flood Mitigation Scheme. The Wilson Road Levee was overtopped during the record October 1993 flood and has since been raised to provide increased protection for the properties within. The Parfitt Road Levee also received substantial modification along the concrete wall section behind the Wangaratta Caravan and Tourist Park, along with raising protection for several isolated dwellings outside the two levees.

KING RIVER

The King River rises near Mt Howitt on the Great Divide and flows north through Lake William Hovell and the townships of Cheshunt, Whitfield, Moyhu and Oxley to form a confluence with the Ovens River at Wangaratta. The upper King River catchment is steep topography down to Moyhu and has a very rapid stream flow that minimises the ability to provide an early flood warning for that area based on stream flows.

Historically, severe flooding has occurred in 1851, 1870, 1917, 1974, 1981, 1993, 1998 and 2010. The 1917 event became a tragedy when six people lost their lives on 8th June after a dray overturned near the junction with the Ovens River in Wangaratta. The October 1993 flood caused record flows and severe damage along the mid and lower catchments of the King River and its main tributaries including the Black Range Creek, Hurdle Creek and Boggy Creek.

Rural City of Wangaratta Flood Emergency Plan – A Sub-Plan of the Municipal Emergency Management Plan

- 26 -

In September 1998, intense rainfall was experienced in the upper catchments of the Ovens, King and Kiewa Rivers. The King River catchment responded with record flows being measured in the upper catchment. In Cheshunt, flood levels were 300 mm above the October 1993 levels, however north of Docker Road flood levels for this event were below the levels experienced in October 1993. It is believed the relatively dry catchment prior to the 1998 event contributed to this anomaly. Around Cheshunt, Whitfield and Moyhu extensive rural inundation and damage occurred. Residents of the Gentle Annie Caravan Park near Whitfield were relocated. Severe damage occurred through gravel deposits on adjoining floodplains, particularly in the upper reaches, that required removal to ensure minimal damage to the farm land abutting the river network. Major breakaways in the river channel required emergency works at several locations and where necessary, bridge repair works and road reinstatement works were undertaken to ensure the road network continued to function.

The 1998 flood event has been recognised as having an equivalent average return interval (ARI) of approximately 35 years while the 1993 and 1974 events were equivalent to an ARI of 120 years and ARI of 70 years respectively (Source: NECMA). Since then floods have occurred in September and December of 2010 and as recently as March 2012. The major flood of early September 2010 again caused considerable rural damage with severe bank erosion and the need to undertake costly modifications to the approach abutments at the Gentle Annie bridge near Whitfield. A comprehensive flood mapping study of the King River tributaries was undertaken by the North East Catchment Management Authority and Rural City of Wangaratta with the final report released in December 2004 - (Reference: 25.7 King River Tributaries Flood Mapping Study.pdf)

FIFTEEN MILE CREEK (ONE MILE CREEK AND THREE MILE CREEK)

The Fifteen Mile Creek rises near Wattle Range Road a few kilometers east of Tolmie and flows north through Greta South to Wangaratta. The upper Fifteen Mile Creek catchment is steep topography down to Greta South and has a very rapid stream flow that once again minimises the ability to provide early flood warning based on stream flows in this area. Near Greta West the Fifteen Mile Creek divides into the One Mile Creek system and the Three Mile Creek system.

The One Mile Creek is further divided into two components, the main one being a theoretically throttled flow into the Wangaratta urban area with excess being conveyed by the diversion channel beside the Hume Freeway and into the King River. The Three Mile Creek is an uncontrolled stream that skirts the west side of Wangaratta where it rejoins with One Mile Creek near Yarrawonga Road, and then flows into the Ovens River several kilometers downstream of the city. Most of the urban area flooding that occurs in Wangaratta is along these two streams.

The May 1974 flood caused above floor flooding of houses along the One Mile Creek between Cribbes Road and Yarrawonga Road, and houses were flooded along Three Mile Creek. It should be noted that flooding of this magnitude is unlikely in the future due to structural mitigation works undertaken since this event. In the period between then and the October 1993 flood, substantial residential development had occurred along the Three Mile Creek and this, combined with completed construction of the Freeway Diversion Channel just prior to the 1993 event, resulted in a reduction of houses flooded along the One Mile Creek compared to the Three Mile Creek. The Diversion Channel was estimated to have diverted some 60% of the water that would normally have flowed down the One Mile Creek, into the King River. This resulted in lower levels in the One Mile Creek down to about Rowan Street where the backup effect of water in the Three Mile Creek started to increase flood levels. In 1993 houses were flooded above floor level on the One Mile Creek and houses similarly affected on the Three Mile Creek. Lowering of the sill into the Diversion channel has been undertaken Rural City of Wangaratta Flood Emergency Plan – A Sub-Plan of the Municipal Emergency Management Plan

- 27 -

to allow floodwater to divert much earlier in an event and now provides further protection for residential properties along the One Mile Creek. A comprehensive study of flooding in the Fifteen Mile Creek catchment was undertaken by the North East Catchment Management Authority with the final report released in July 2006 - (Reference: 14.51 Fifteen Mile Creek Floodplain Management Plan.pdf)

NON RIVERINE FLOODING

Localised flooding does occur on a frequent basis, and appears to be an increasing phenomenon, such as experienced in the 2010 flood event, north of Wangaratta in an area roughly bounded by Boralma, Bowser and Boorhaman. The catchment for this area is in the Springhurst hills east of the Hume Freeway and whilst there is no major stream in the area the innumerable smaller valleys and relatively cleared country generate considerable runoff. Once west of the Melbourne - Sydney Railway the extremely flat riverine plains slow the progression of runoff causing a number of small drains and depressions to rapidly fill causing overland floodwater to encroach onto properties and houses that very rarely see flooding. The 2010 and 2012 events saw similar localised flooding from the eastern flank of the Warby Ranges, which impacted on the rapidly developing semi-rural properties as far south as Hamilton Park near Glenrowan, to the more intensely developed areas near Waldara. It is only since this development has occurred and storm-water runoff has been concentrated into defined drainage systems that the potential for flooding of adjacent properties has become apparent.

Although Flood Mitigation schemes have been developed, it is acknowledged works in place prior to 1993 were not entirely adequate. Further measures have been taken but cannot be assumed to be a complete answer.

Dam Failure Flooding resulting from failure of the following dams is likely to cause significant structural and community damage within the Rural City of Wangaratta.

More details about flood intelligence and its use can be found in the Australian Emergency Management Manuals flood series.

APPENDIX D - FLOOD EVACUATION ARRANGEMENTS

There are five stages in the evacuation process: decision, warning, withdrawal, shelter and return.

Phase 1 - Decision to Evacuate The Incident Controller may make the decision to evacuate an at-risk community under the following circumstances:

. Properties are likely to become inundated; . Properties are likely to become isolated and occupants are not suitable for isolated conditions; . Public health is at threat as a consequence of flooding and evacuation is considered the most effective risk treatment. This is the role of the Health Commander of the incident to assess and manage. Refer to the State Health Emergency Response Plan (SHERP) for details); . Essential services have been damaged and are not available to a community and evacuation is considered the most effective risk treatment.

The following should be considered when planning for evacuation:

. Anticipated flood consequences and their timing and reliability of predictions; . Size and location of the community to be evacuated; . Likely duration of evacuation; . Forecast weather; . Flood Models; . Predicted timing of flood consequences; . Time required to conduct the evacuation; . Time available to conduct the evacuation; . Evacuation priorities and evacuation planning arrangements; . Access and egress routes available and their potential flood liability; . Current and likely future status of essential infrastructure; . Resources required to conduct the evacuation; . Resources available to conduct the evacuation; . Shelter including Emergency Relief Centres, Assembly Areas etc.; . Vulnerable people and facilities; . Transportation; . Registration . People of CALD background and transient populations; . Safety of emergency service personnel; . Different stages of an evacuation process. The decision to evacuate is to be made in consultation with the MERO, MERC, DHS, Health Commander and other key agencies and expert advice (CMA’s and Flood Intelligence specialists). Rural City of Wangaratta Flood Emergency Plan – A Sub-Plan of the Municipal Emergency Management Plan - 44 -

The table below details triggers for evacuation, if these heights are predicted or are likely to occur evacuation should be considered.

* Detail for these tables will be added once flood evacuation plans are developed for this MFEP coverage area

Sector* Gauge Trigger

The table below details time required to evacuate established areas.

Sector* Likely time required for evacuation (including resource assumptions)

Phase 2 – Warning Warnings may include a warning to prepare to evacuate and a warning to evacuate immediately. Once the decision to evacuate has been made, the at-risk community will be warned to evacuate. Evacuation warnings can be disseminated via methods listed in part 3 of this plan.

Evacuation warning messages will be developed and issued by VICSES in consultation with the MERO, MERC, DHS and other key agencies and expert advice (CMA’s and Flood Intelligence specialists).

Phase 3 – Withdrawal Withdrawal will be controlled by VICPOL. VICSES will provide advice regarding most appropriate evacuation routes and locations for at-risk communities to evacuate to, etc.

VICSES, CFA, AV and Local Government will provide resources where available to support VICPOL/VICROADS with route control and may assist VICPOL in arranging evacuation transportation.

VICPOL will control security of evacuated areas.

Evacuees will be encouraged to move using their own transport where possible. Transport for those without vehicles or other means will be arranged.

Possible Evacuation Routes to be used:

Sector* Evacuation Route Evacuation route closure point and gauge height of closure

Landing zones for helicopters are located at:



Rural City of Wangaratta Flood Emergency Plan – A Sub-Plan of the Municipal Emergency Management Plan - 45 -

Special needs groups will be/are identified in Council’s ‘residents at risk’ register. This can be done through community network organisations. Further information on Council’s ‘residents at risk’ register can be obtained from VicPol and MECC Central/Crisisworks

Phase 4 – Shelter Relief Centres and/or assembly areas which cater for people’s basic needs for floods may be established to meet the immediate needs of people affected by flooding. Relief centres are listed in Appendix E of the Rural City of Wangaratta MEMPlan.

Sector Relief Centre/Assembly Area Comments (include address)

Refer to Appendix E of RCoW MEMP

VICPOL in consultation with VICSES will liaise with Local Government and DHS (where regional coordination is required) via the relevant control centre to plan for the opening and operation of relief centres. This can best be achieved through the Emergency Management Team (EMT).

Animal Shelter

Animal shelter compounds will be established for domestic pets and companion animals of evacuees. These facilities will be documented in the RCoW Municipal Emergency Management Welfare Plan, a sub-plan of the MEMP.

Sector* Animal Shelter Comments (include address)

Caravans

Caravans maybe evacuated to the following locations:

Sector* Caravan evacuation location Comments (include address)

Phase 5 – Return Return will be consistent with the Strategic Plan for the Return of Community

The Incident Controller in consultation with VICPOL will determine when it is safe for evacuees to return to their properties and will arrange for the notification of the community.

VicPol will manage the return of evacuated people with the assistance of other agencies as required.

Considerations for deciding whether to evacuate include:

. Current flood situation; . Status of flood mitigation systems; . Size and location of the community; . Access and egress routes available and their status; . Resources required to coordinate the return; . Special needs groups; . Forecast weather; . Transportation particularly for people without access to transport

Rural City of Wangaratta will establish a sandbag collection point at

. Bachelors Green

APPENDIX E - FLOOD WARNING SYSTEMS

Flood Warning Flood Warning products and Flood Class Levels can be found on the BoM website. Flood Warning Products include Severe Thunderstorm Warnings, Severe Weather Warnings, Flood Watches and Flood Warnings.

Flood Bulletins VICSES distributes flood emergency information to the media through “Flood Bulletins”. Flood Bulletins provide BoM Flood Warning information as well as information regarding possible flood consequences and safety advice, not contained in BoM Flood Warning products. VICSES uses the title Flood bulletin to ensure emphasis is placed upon BoM Flood Warning product titles.

The relevant VICSES Region Headquarters or the established ICC will normally be responsible for drafting, authorizing and issuing Flood Bulletins, using the One Source, One Message system.

Flood Bulletins should refer to the warning title within the Bulletin header, for example Flood Bulletin for Major Flood Warning on Yarra River.

Flood Bulletins should follow the following structure

. What is the current flood situation; . What is the predicted flood situation; . What are the likely flood consequences; . What should the community do in response to flood warnings; . Where to seek further information; . Who to call if emergency assistance is required. It is important that the description of the predicted flood situation is consistent with and reflects the relevant BoM Flood Warning.

Flood Bulletins should be focused on specific gauge (or in the absence of gauges, catchment) reference areas, that is the area in which flood consequences specifically relate to the relevant flood gauge.

Flood Bulletins should be prepared and issued after receipt of each Flood Watch and Flood Warning from the BoM, or after Severe Weather or Thunderstorm Warnings indicating potential for severe flash flooding.

To ensure flood bulletins are released in a timely manner, standardised flood bulletins may be drafted based on different scenarios, prior to events occurring. The standardised flood bulletins can then be adapted to the specifics of the event occurring or predicted to occur.

APPENDIX G – LOCAL KNOWLEDGE ARRANGEMENTS

As control agency for flood in Victoria, VICSES is committed to ensuring the incorporation of local knowledge in decision making before, during and after incidents.

Information from community sources including, but not limited to; observations, historical information and information about current and possible consequences of an incident; may be utilised to help inform the process of incorporating local knowledge into decision making during an incident. Community observers, Local Information Officers (LIOs) and other agency networks identified in this plan will help support this process.

LIOs provide a key communication interface to community observers and other sources of local knowledge.

The process to identify community observers for the Rural City of Wangaratta will populate the following tables at a later date:

Community Community Observer LIO Contact Key Areas of local knowledge expertise Observer Name contact details

For the VICSES Wangaratta Unit the Local Information Officer identified is:

LIO Name LIO contact details Community Observer contacts

Important Notes:

These arrangements do not delegate any responsibility for operational decisions to community observers and/or existing agency networks. They do not authorise or endorse community observers and existing agency networks to direct operational activity, including the management of flood levees.

Information provided from sources of local knowledge must be processed and validated before it can become intelligence to inform decision making.
